CONCLUSIONS: The Chinese MSTS scoring system is a reliable and valid instrument with well-accepted psychometric properties. The factor analysis indicated a 1-factor model with acceptable goodness of fit. 23.5 ± 6.3, p = 0.005), which indicated a good discrinimant validity of the Chinese MSTS. Patients undergoing amputation surgery had remarkably lower MSTS score than patients undergoing limb-salvage surgeries (18.8 ± 5.4 vs. The test for internal consistency showed a Cronbach's α of 0.86 for the MSTS. ![]() The ICC was 0.91 (95% confidence interval (CI) = 0.85-0.96) for the test-retest reliability and 0.90 (95% CI = 0.86-0.93) for the inter-observer analysis. RESULTS: The mean MSTS score was 21.5 ± 7.1. The construct validity was evaluated with the factor analysis. The discriminant validity was evaluated through comparison of the MSTS score between patients undergoing amputation surgeries and those undergoing limb-salvage surgeries. The internal consistency was evaluated by Cronbach's α, with a value >0.70 considered acceptable. The inter-observer and test-retest reliability was analyzed with intra-class correlation coefficient (ICC). The reliability of Chinese MSTS was evaluated through test-retest analysis, inter-observer analysis and internal consistency. Assessment of psychometric properties was carried out through reliability and validity test. All the patients completed the clinical assessment with the Chinese MSTS and the Chinese Toronto Extremity Salvage Score (TESS). METHODS: A cohort of 98 patients who had undergone surgery for lower extremity sarcoma were included. This study aims to investigate the reliability and validity of the Chinese version of the MSTS, and to evaluate functional outcomes of the surgical treatment of lower extremity sarcoma using the Chinese MSTS. N2 - BACKGROUND: The Musculoskeletal Tumor Society (MSTS) scoring system is a disease-specific instrument to determine the physical and mental health for patients with extremity sarcoma. The procedure enables both adequate oncosurgical resection and function preservation.T1 - Functional evaluation for patients with lower extremity sarcoma: application of the Chinese version of Musculoskeletal Tumor Society scoring system. Overall MSTS score was 73.5%.Ĭonclusion : The microsurgical repair of defects is a reliable option that, though not free of complications, is necessary in selected cases. Eighty three percent of the patients remained alive (n = 20), 19 of whom currently have no evidence of disease (NED) Disease recurrence was noted in three patients. Partial epidermal necrosis was evident in four cases. Another patient with internal hemipelvectomy for Ewing’s sarcoma had a dura puncture during resection of sacrum. One of the patients had secondary hemorrhage 10 days after surgery. Complications included, one complete failure of free vascularized iliac crest flap done for reconstruction of a heel defect. Lower limb reconstruction outnumbered upper limb by 6:1. Results : Twenty four patients (age range: 7 - 72 years) who have undergone tumor resection followed by flap coverage were identified. Assessment of Functional outcome (Musculoskeletal Tumor Society score, MSTS) local recurrence, free survival, and disease-specific survival was also made. Perioperative morbidities were also noted including donor as well as recipient site complications. Patients and Methods : The records of patients (n = 24) who underwent microsurgical soft tissue reconstruction subsequent to resection of limb tumour during the period 2006 to 2011 were reviewed. Refinements in surgical techniques have led to increased function preservation and limb salvage. Tumor free-margin surgical resection remains the single most important treatment in the curative therapy of musculoskeletal tumor of limbs. ![]()
